SAN FRANCISCO — With the blizzard that blanketed the Northeast in snow Friday night moving on, cancellations slowed to a trickle late Saturday morning at San Francisco International Airport, officials said.

Only 20 arrivals and 3 departures were canceled as of about 10 a.m., according to duty manager Nancie Parker. About 60 flights were canceled Friday as airlines tried to keep planes from being caught in the heavy snowfall that covered the area.

Boston’s Logan Airport was the last major airport in the area to reopen, Parker said. Officials said they planned to open the airport by 9 a.m., but they may not have a runway open until 8 p.m., according to the airport’s Twitter feed.

There were no canceled flights to or from the northeast at either Oakland or San Jose airports, according to tracking website Flight Stats.
